What exercises? Well, the best place to start is probably your forearms. Wrist flexors and extensors work equally hard to keep you on the wall. There are a lot of devises that will assist you in strengthening these eg. powerball http://www.powerballs.com/, Metolius gripsaver plus http://www.metoliusclimbing.com/product ... aining.htmInstead of investing in these, a fingerboard will be your best exercise device I would think. Doing old fashioned pull ups on these or just anthing else really will help condition your upper body. just remember that climbing is not just about the strength of your biceps, you use your legs just as much and need ++ core strength to build up enough body tension to keep you on the rock. Apart from strength, you need a lot o flexibility too. Just Google climbing training and you will have more than enough exercises to keep you busy. In the end your best bet would be to just get out there and climb as often as possible, focusing on overhangs where extra strength is needed.

As a beginner the most important thing is to learn to climb - so the best training is going climbing. Obviously that is not always possible, so the next thing is build up some strength.

The most basic ability is pull-ups. Do lots of them. Then do more. When you can do 20 in a row (fingers facing away from you) you are ready to move on to finger training, which you can do on a finger board or climbing wall.

It is also important that you train your antagonistic muscles (for climbers these are the pushings muscles) to prevent injuries.

I would definetly agree with Guy, never mind the wall, you will most likely pick up an injury and don't even go near a campus board.
20 pullups?? Jeez, I would say 15 max, anything above is not neccessary and then start adding weights.
Concentrate on longer techinical (face) routes.

Build yourself one of these. I think the best way to train for climbing especially being new, is to climb. Be careful as others have said it is easy to over train and do more damage than good. Also do some exercise to balance your muscle. Do pushing execises, push-ups, bench press, flies, military press and such.

If your looking for general strength then pull ups, push ups and squats are easy to do at home but I rely don’t advise the “bed room warrior” tactic, its hard to keep up and gets very boring, very fast…
